Have an rodi from the filter guys when they were in business. Added components to it since then. From source water to output the order is as follows:
Source water > 1 micron sediment filter > 1 micron carbon block filter > 1 micron carbon block filter > BRS chloramine monster > dual 75 gpd RO membranes > mixed DI resin > storage tank.
Storage tank is 65 gallons. Resin from brs is exhausted with about 1 fill of the tank. I run the rodi on a Smart Buddie Booster Pump as well. Prefilters changed about every 3 to 4 months. Membranes twice a year. And as mentioned, resin about every fill of the storage tank. Looking to stop changing resin so often if possible.
Initial tds flush from prefilters, chloramine monster and membranes is on the mid 300s. I let that drain for about 10 mins until its closer to 9-10, then start supplying the resin.
